.NET Core 中 Session的使用

原文链接：http://beidouxun.com/Articles/Details/50bd1241-bc05-43df-9cbb-d5c00ced33ac

.NET Core中使用Session步骤如下：

1、安装Microsoft.AspNetCore.Session    NuGet包

 

2、修改Startup.cs 添加相关服务，services.AddSession()和app.UseSession()

// This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddIdentity<ApplicationUser, IdentityRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

            // Add application services.
            services.AddTransient<IEmailSender, EmailSender>();

            //Add session
            services.AddSession();

            services.AddMvc();
        }

 // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseBrowserLink();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            app.UseStaticFiles();

            app.UseAuthentication();
          
            app.UseSession();

            app.UseMvc(routes =>
            {
                //Default route
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }

 

3、Session 用法

引用

using Microsoft.AspNetCore.Http;

Session写入

HttpContext.Session.SetString("key", "value");

Session读取

HttpContext.Session.GetString("key");
